PROCESS CONTROL IMPROVEMENT
The benefits from process control improvement (PCI) originate from increases in process efficiency, flexibility, and capacity. Often, there is a tradeoff where an increase in flexibility or capacity is accompanied by a decrease in efficiency. Better measurements, process knowledge, online metrics, and an enhanced proportional-integral-derivative (PID) can provide a more intelligent and effective optimization that minimizes the tradeoff between benefits.
Process knowledge improves as measurement accuracy is increased. Simulations are better verified, material and energy balances closed, better setpoints found, and more accurate metrics computed. The door is then opened to ...
